NEWARK — The babysitter of a 4-year-old Newark girl who died hours after being left home alone with three other children has been arrested, authorities said.

Naira Bennett, 4, was pronounced dead at University hospital at 7:11 p.m. Wednesday. She was found unresponsive in an apartment on North Munn Avenue at about 10:45 a.m, according to a release issued by the Essex County Prosecutor's Office.

Sakita Covington, 38, who also lives in the Bradley Court complex, was charged with four counts of endangering the welfare of a child and one count of aggravated assault.

An autopsy will be performed to determine how the girl died, officials said. Neighbors said the young girl was reaching for a toy underneath a bed when it fell on her.

The other children were not harmed, according to Katherine Carter, a spokeswoman for the prosecutor's office. Each is under the age of 4, she added.

Carter said she was not authorized to disclose where the babysitter was or why she might have left the apartment.

Iesha Wiggins and Lakeya Harris, both 19, live next door to the apartment where Bennett died. They said Covington lives in the apartment, and is married with two young children of her own. Bennett's family does not live in the apartment, they said.

Harris said police and rescue personnel swarmed the building on Wednesday morning, and some of the children who were left unattended may have been Covington's own. Both said they were saddened by what happened, and did not know where Covington allegedly went or why she would leave four young children inside the apartment unattended.

"I think it's irresponsible, stupid," said Harris. "What fool leaves a little kid at the house all by himself."
